"Nasty" is the second single from Janet Jackson's third studio album, Control (1986). Released in 1986, the single peaked at number three on Billboard Hot 100 and number one on the Hot R&B/Hip-Hop Songs, and remains one of Jackson's signature songs. The line "My first name ain't baby, it's Janet – Miss Jackson if you're nasty" is a well-known catchphrase and has frequently been used in pop culture in various forms.

After arranging a recording contract with A&M Records in 1982 for a then sixteen-year-old Janet, her father Joseph Jackson oversaw the entire production of her debut album, Janet Jackson, and its follow-up, Dream Street (1984).[4] Jackson was initially reluctant to begin a recording career, commenting "I was coming off of a TV show that I absolutely hated doing, Fame. I didn't want to do [the first record]. I wanted to go to college. But I did it for my father ..." and elaborated that she was often in conflict with her producers.[5] Amidst her professional struggles, she rebelled against her family's wishes by marrying James DeBarge of the family recording group DeBarge in 1984. The Jacksons disapproved of the relationship, citing DeBarge's immaturity and substance abuse. Jackson left her husband in January 1985 and was granted an annulment later that year.[6]

Jackson subsequently fired her father as her manager and hired John McClain, then A&M Records' senior vice president of artists and repertoire and general manager.[7] Commenting on the decision, she stated, "I just wanted to get out of the house, get out from under my father, which was one of the most difficult things that I had to do, telling him that I didn't want to work with him again."[5] Joseph Jackson resented John McClain for what he saw as an underhanded attempt to steal his daughter's career out from under him.[8] McClain responded by saying "I'm not trying to pimp Janet Jackson or steal her away from her father."[8] He subsequently introduced her to the songwriting and production duo James "Jimmy Jam" Harris III and Terry Lewis, and Jackson and the duo started working on a third studio album for Jackson, titled Control, in Minneapolis.[9] "Nasty" was Jackson's autobiographical account of confronting abusive men who tried to force their hand on her in Minneapolis. She said,

The danger hit home when a couple of guys started stalking me on the street. They were emotionally abusive. Sexually threatening. Instead of running to Jimmy or Terry for protection, I took a stand. I backed them down. That's how songs like 'Nasty' and 'What Have You Done for Me Lately' were born, out of a sense of self-defense. Control meant not only taking care of myself but living in a much less protected world. And doing that meant growing a tough skin. Getting attitude.[10]

Jimmy Jam built the melody for this song around a sound from his then-new Mirage keyboard: "It [had] a factory sound that was in there... more of a sound-effect type of sound," he recalled. "I've always been - probably from being around Prince - interested in using unorthodox types of things to get melodies and sounds. That was a very unmelodic type of sound, but we found a way to build a melody around it."[11]

In August 1999, Missy Elliott revealed she was working with Jackson on an updated remix for the song; its working title was "Nasty Girl 2000".[12][13] The following year, Elliott's close friend Aaliyah was added to the track, however due to undisclosed reasons the record was never released.[14]

"Nasty" is set in common time with a key of F minor. Jackson's vocal chords ranges between the tonal nodes of Eb4-Eb5. The song is in a medium dance groove tempo of 100 beats per minute.[15] At the beginning of the song, Jackson shouts, "Give me a beat!". The song is about respect as she tells all her male admirers "better be a gentleman or you'll turn me off".[16] For Los Angeles Times, Jackson's approach is hard and aggressive in the song.[17]

Billboard's reviewer Steven Ivory called "Nasty" a "hard-funk" song, along with other tracks from Control.[18] Rob Hoerburger from Rolling Stone remarked that "on cuts such as 'Nasty' and the single 'What Have You Done for Me Lately' Janet makes the message clear: She's still basically a nice girl but ready to kick some butt if you try to put her on a pedestal".[19] William Ruhlmann of AllMusic picked the song as one of the album's highlight.[20] Website Scene 360° commented that it was a confident, sassy song and influenced pop music in the following years of its release.[16]

Jackson sang "Nasty" live at the Grammy Awards of 1987, wearing an all-black outfit, along with Jam and Lewis and dancers.[21] She also has performed the song on all of her tours. It was first performed on the Rhythm Nation Tour in 1990.[22] On the Janet World Tour which happened in 1993 and continued throughout the two following years, the song was the second to be performed along with "Nasty", with the singer wearing gold jewelry.[23] The song was performed during a "frenzied" medley with "What Have You Done for Me Lately" and "The Pleasure Principle" on The Velvet Rope Tour in 1998.[24] The medley at the October 11, 1998 show in New York City, at the Madison Square Garden, was broadcast during a special titled The Velvet Rope: Live in Madison Square Garden by HBO. It was also added to the setlist at its DVD release, The Velvet Rope Tour – Live in Concert in 1999.[25] During the All for You Tour in 2001 and 2002, "Nasty" was performed in a re-worked version, during a medley with "Control" and "What Have You Done for Me Lately". According to Denise Sheppard from Rolling Stone, it was "another crowd favorite; perhaps best dubbed as the 'bitter' portion of the night", also adding that "this performer - who has been performing onstage for twenty-eight years - knows what the crowd comes for and gives it to them in spades".[26] The February 16, 2002 final date of the tour at the Aloha Stadium in Hawaii, was broadcast by HBO, and included a performance of it. This rendition was also added to the setlist at its DVD release, Janet: Live in Hawaii, in 2002.[27]

On September 9, 2006, Jackson went to France to perform "Nasty" and new single "So Excited" at NRJ's Back to School concert, as part of promotion for her ninth studio album 20 Y.O..[28] While on The Oprah Winfrey Show, she was interviewed and performed both tracks again. The show aired on September 25, a day before 20 Y.O.'s release in the United States.[29] A few days later, the singer performed on Today's Toyota Concert Series in Rockefeller Center, in New York City, to promote 20 Y.O. The setlist also included "So Excited" and "Call on Me".[30] For her first tour in six years, titled Rock Witchu Tour, Jackson performed "Nasty" as part of it.[31] Jackson made a surprise appearance on the ninth season finale of American Idol in 2010 to perform a medley of "Nothing" and "Nasty" after joining the contestants to perform a rendition of her hit ballad "Again". She wore a black suit with red-lined sleeves.[32] It also added to her concert at Essence Music Festival in New Orleans, in July 2010, which she headlined.[33] It was also performed during her Number Ones: Up Close and Personal tour in 2011. John Soeder from Cleveland.com commented, "Yet the emphasis was on high-energy dance numbers, including “Miss You Much,” “Nasty,” “When I Think of You” and other infectious blasts from the past, complete with pneumatic grooves and icy synthesizers. The net effect was akin to squeezing into an old pair of acid-washed jeans."[34][35] It is also included in her current 2015-2016 Unbreakable World Tour.

In the fall of 1989, NBC aired a pilot movie, and later a 13-episode mid-season replacement series, called Nasty Boys about a group of North Las Vegas undercover cops and their unorthodox methods working in a narcotics unit. The theme music was Jackson's "Nasty", performed by Lisa Keith, though the lyrics were slightly changed to make the song more pertinent to the storyline.

USA Network used "Nasty" in a promo for the seventh season of the series Psych, with past snippets from the show put together to create the song's call and response portion.[37]Buckcherry sang the song live as a tribute to Jackson during MTV's MTV Icon special in 2001.[38]

Britney Spears has paid homage to "Nasty" multiple times throughout her career; she performed live covers of "Nasty" and "Black Cat" on the "Baby One More Time Tour".[39] She also yelled "Stop!" in the single version of "(You Drive Me) Crazy" pays homage to Janet saying "Stop!" in the "Nasty" music video. The single version of the song, titled the "The Stop! Remix", also references "Nasty". The chair routine in the song's music video pays homage to Jackson's "Miss You Much" video. Additionally, her single "Boys", released as the fourth single from her Britney album, references "Nasty" in the line "get nasty", with the song being described as "cut-rate '80s Janet Jackson" by Entertainment Weekly.[40] Spears also pays homage to the song in "Break the Ice", released as the third single from her fifth studio album Blackout, in the line "I like this part", which references Janet saying "I love this part" in "Nasty". Spears' official site said she was "stopping the song à la Janet Jackson to say, "I like this part. It feels kind of good."[41][42] The opening scene of her "Ooh La La" video also pays homage to Jackson's "Nasty" video, with MSN Music saying "The clip plays out like a more kid-friendly version of Janet Jackson's "Nasty" video, with Spears and her kids taking in a movie when mom is suddenly transported into the on-screen action."[43]
